CAN-MARKING DEVICE.

. To all whom it may concerm. i

Myinvcntion consists in certain new and vstampingyor impressing -'Beit known that I, THOMAS O. MAT'rnEws,

a citizen of the United States, and residing,

in the borough of Avalon, in the countyof Allegheny and State of Pennsylvania,'have invented ordiscovered new and useful Improvements in Can-Marking Devices, of which the following is a specification.

usefu'l improvements in mechanism for letters, numbers orother characters-or ma (son sheet metalarticles such as capsor covers for cans, bottles 'co 1 ta'1n1ng,t 1e desired characters which are I a djustably. and r'emovably mounted and arand othegre'ceptacles. It may be applied to 'a'ny-typeof stam )ing-or impression press orsimilar device. he article to bemarked is engaged b coacting male. and female type ranged. in 'l'io'lders which are in turn secur- I able tothe press. The female type are preff erabIy'mO mted on a removable form which is secured in the upper holder attached to the plunger of the'pi'css, while the male t 1e are mountodin-a holder which is securer to the bed plateol the press. The form in I. whichthe female type are mounted is shown provided with a slot or slots, of which there may be any 'dcsirednumberas dictated h the number of lines-of characters desirm, through which the type extend downwardly,

beinrprefzented from falling through .the

slot y their shoulders. The male type are mounted in a slot or slots in the lower older and are prevented from dropping out of placeby meansof the bottom oi: the slot,

which bottom'may be of hardened steel to resist'therimpact. It iscvident that in the A use ofmyirivention any desired number of linesof characters ma be used and any number ofcharacters r esn'ed in each line,

dependent on the area of the holders and the length anddnumber of the slots' The type are preferably marked on their-reverse ends with the character which is impression ends and also W1 provided on the i3 the same toindicate the direction in which the are tobe turned to be properly set.

Ii i the accompanying drawings,' Figure '1 isa perspective of'a stamping press fitted with my invention Fig. 2 1s airont view of I the up or and'lower holders on an enlarged scale; .ig. 3 a side elevation of. the same showing two rows of type; Fig. 4 is an in- 5 verted plan view ofthe upper holder block a mark undertype and Fig. 6 shows a similar view of a female type with acbottom plan view attached. The following is a detailed description of the drawings.

1 is astamping press of well known design. My invention may be applied to any form-of illustrates the operation. 2 is the plun er and 3 the plunger socket.

4 is the bed plate. his the upper holder,-which to fit the plunger socket 3 is in thiscase provided with a rigid spindle, 6 adapted to engage said principles of'my invention in cess Band also extending fro'm'side to side of of thefemale type mounted in form 10, said when an mpression is being made.

12 is a back late attached to holder 5 and extending across the rearof recess 8 to limit the movement of form 10. The forni 10 is provided with knob 13 for its mani ulatioln 14 is a spring pin mounted in hOlL er 5 and adapted to enter a hole in the wallof form; 10 and hold the same rigidly in place in said rceessS when-the press is pro ared for opera.- tion. By drawing out sai pin a ainst its coiled sprin ,i-he form may be readily slipped from the'ho der when desired.- Sair form 10 is provided with one or more slots 1516 in which are mounted or set the female type 1 6-. 1 6, said type being provided with shoulders 1.7-17 to prevent their dropping down throughsaidslots. I have shown two type slots in Fig. 4 but it will be understood t lat any desired number of slots maybe provided and the' same may be of any desirer length, controlled of ,course by the. area of the form ed in the form 10 are the female type shown in Fig. Gland blocks or s acers aroused to fill in the slots where sullieient type to fill the same are not used.

The lower holder is composed of a bottom and formyFig. 5'is a perspective of a male ress but the one shown is well known and.

socket and be secured therein by means oft in the floor of re used. The type which are preferably mountrecess 8 across its lower-face froin'side' to side holder 5, into which recess extend the shanks -type bearing against the bottomof said recess plate 18 Which may be attached to the platform 4 of the press with set screws or other.

conrenient means, and block 19 which is proyided with one or more type slots 2020, which correspond in number to the slots 15-15 in form 10. In said slots 202O are mounted the male type 21-2 1 which may be secured. thew-i by means of blocks or spacers or in any other convenient manner:

T he reverse ends of type 161 6 are marked with the letter or number which the type will stamp, I lso with a small dot or mark, 22, to i icatc the proper position in which the type should be placed to print uniformly, the .pc being set upside down in the form 10.

' operatioi'i of my invention as folows:--".lhe for-1n 10 is removed from recess i. holder and the proper feiualetype --1fi inserted dmvnwardly therein until suspended from their shoulders 17-17. Suilicient hlaniis are also introduced in a similar manner to block the type rigidly in place. The form is then slipped into recess 8 and locked therein by means of spring pin 1%, the tops of the type bearing against the material of the block T 10 proper male type, Zr- 2 to correspond to the said fenude type both in character and arrangelncnt, are next introduced into slots of the lower holder and blocked therein. Thus under each i type there is located a coacting male type bearing the same character. The upper holder is now placed in the press by. slipping its spindle 6 into socket 3 and securing the same therein by z'iieans-of set screw 7 The lower holder is new placed on platform 4 and secured thereto as aforesaid. The cap or other article to be nun-lied. is now rested on the top of male type 2l-21 and the press is operated depressing plunger 2 thus forcing the female ty e 16*16 down on. the article to be married. The type ill-21, resisting the depression of-the arti-i ole, force the material thereof into the female typo 48-4 6, thus forming raised numbers, letters or other characters in the material of articie.

If desired the position of the male and 5e inale type may be reversed, but I prefer the 'cnicnt shown. v The advantages of in inventionover the sent iniethods ot' impressing or marking articles of such character are self-evident. The data which placed on caps, covers or lids of receptacles not constant, but, as in the case of food products for instance, inust fro uently he changed to indicate date of pat-ling, character of goods 520. it a separate stamp Were required for each change, the expense would be prohibitive could'the marking be advantageously omitted. I provide means whereby the data canbc set uph'oin individual type in a few moments by the most unskilled labor and the exact data dcsired stamped on the articles in one i1npres sion. 1 thus do away with a inultiplieity of stamps, duplicates of each other in many 1nstances except for a single characten In the use of Such stamps great care must be observed in selecting; the proper stamp in each case from quantity of similar stamps. The arrangement and construction of parts shown by me is both simple and novel.

I have shown my invention applied to a 'Well known type of press but its appli ability to any design of press is evident. The durability of my invention is also of great advantage. When type heconieso worn as not to properly coact to give a clear impression, new type may be substituted at trifling expense and the equipment is r original condition. The holders and form are practically indestructible.

W hat i desire to claim is:-

In a can marking device, the combination of a press having a stationary bed and a plunger, a slotted block secured to said bed, type members set in the slots ofsaid block, asecond block secured to said plunger provided with a recess on itsiowor face, a slotted type form occupying a portion oi said recess and shouldered tvoe members bearing thetop of said- 7055 arddcpending through the siots of sin form, said iii-st and last mentioned type members co-acting to mark the can, substantially as and for the purpose set forth.
